A system apparatus and method of monitoring in a secured fashion the access, storage and retrieval of information, using a networked modular wireless device. The system may include a network of wireless, Wi-Fi devices (or any other wireless communication mechanism such as GPRS, GSM, iDen), or Nodes, each one of them possibly controlling the access to a medically sensitive object, such as a drawer (or cabinet) or to a medical device, or to another information source, item of equipment, drug, etc as well as tracking via RFid readers the access to the records or information contained in it. In the case of a physical file, each file has an RFid tag on it that is being read when removed or returned to the cabinet. Access to the cabinet and physical records, or to the medical device is monitored by reading the RFiD identity card of personnel accessing the cabinet or medical devices. In addition to controlling the access to the cabinet or medical device by controlling the cabinet lock (or in the case of a small medical device, the lock of an IV, injection device, specimen collection unit, or of a large medical device such as a defibrillator), the node can alert electronically by sending a message to the controlling unit, or by sending a physical alert (such as an alarm signal), when unauthorized personnel is attempting to access the cabinet, the files or devices. The system is useful in the context of monitoring the information contained in physical files, such as medical information, and can be used for access to medical devices, in order to better monitor the authorization rights of personnel participating in processes such as drug delivery or specimen collection. A control unit monitors activity at a plurality of nodes, and assists in storing the list of authorized personnel and files, and can store electronically captured information regarding the physical files (for example, the reason for accessing the file and reasons for changes in it) or medical device. The system can communicate with other information management systems.

A biopsy instrument with an internal specimen collection mechanism is provided.

Controlled-specimen-sampling oral devices are described, implanted or inserted into an oral cavity, built onto a prosthetic tooth crown, a denture plate, braces, a dental implant, or the like. The devices are replaced as needed. The controlled specimen sampling may be passive, based on a dosage form, or electro-mechanically controlled, for a high-precision, intelligent, specimen sampling. Additionally, the controlled sampling may be any one of the following: sampling in accordance with a preprogrammed regimen, sampling at a controlled rate, delayed sampling, pulsatile sampling, chronotherapeutic sampling, closed-loop sampling, responsive to a sensor's input, sampling on demand from a personal extracorporeal system, sampling regimen specified by a personal extracorporeal system, sampling on demand from a monitoring center, via a personal extracorporeal system, and sampling regimen specified by a monitoring center, via a personal extracorporeal system. Specimen collection in the oral cavity may be assisted or induced by a transport mechanism, such as any one of, or a combination of iontophoresis, electroosmosis, electrophoresis, electroporation, sonophoresis, and ablation. The oral devices require replacement at relatively long intervals of weeks or months. The oral devices and methods for controlled specimen sampling apply to humans and animals.

A biological material test strip and adjacently-located reference color chart are affixed to a lid portion of an all-in-one specimen cup to perform color-based reaction testing of collected biological specimens in an uncalibrated environment. After specimen collection, the lid portion is secured to a container portion of the specimen cup. The cup may then be rotated into an upside down position causing the specimen, under the force of gravity, to pass from the container portion and into a volume of the lid portion, such that the test strip is exposed to the specimen as it is received into the volume of the lid portion. An image of the exposed test strip and adjacently-located reference color chart may then be captured and processed to identify any color matches between the individual test pads on the test strip and the corresponding sequences of reference color blocks on the reference chart.

Devices and systems for extracting, purifying and amplifying nucleic acids, and methods for use of such devices and systems. The devices have top sections which include a plurality of syringe vessels with applicable reagent materials, as well as a channel for a specimen collection dropper. Plungers force the materials sequentially into reaction chambers in the middle sections. Once the samples are extracted and purified, they are drawn by a vacuum into PCR devices where they are subjected to denaturing, annealing and extension steps and amplified. Interrogation of flow cells provide real-time quantitative detection.

A sterile aqueous specimen collection fluid containing a buffer, an aliphatic aldehyde at a concentration of 0.15M to 3.4M, and one or more heavy metal salts at a concentration of 0.2x10-3M to 0.2M, and having a pH of 6.8 to 8.0. Also disclosed is a method of colleting a specimen with such a fluid for haematological analysis.

A specimen collection container having a separation chamber includes a first chamber, a second chamber, and a valve located between the first chamber and the second chamber. In an open position, the valve permits fluid communication between the first chamber and the second chamber. In a closed position, the valve maintains fluid isolation between the first chamber and the second chamber. A fluid stream passes from the first chamber to the second chamber through the valve permitting a predetermined volume of fluid to pass from the first chamber to the second chamber. When the predetermined volume of fluid passes to the second chamber, the valve transitions from the open position to the closed position so that additional fluid of the fluid stream received by the first chamber is maintained in the first chamber in fluid isolation from the predetermined volume of fluid contained in the second chamber.
